Crankshaft pully?

[t-vicky]

Am taking my 350 Chevy apart to put a new camshaft in it. I am to the part where you pull the harmonic balancer off & it is saying NO WAY.  I have a 3-prong puller on it with the 3-point plate bolted on. It just wont move.  Am worryed  about breaking the puller. I put a 2-ft. cheater bar on the wrench & went a full turn & no movement.  Anyone got any ideas?  Thanks, Roger

some of them are on really tight.....


and you did remove the center bolt right....


one thing.... is your puller center stud like 5/8-20 or 1/2 inch acme...

the ones that are acme thread have less pull to start... less leverage...

the finer thread   pulls more per torque input....

and make sure the tip on the puller is greased.... so the alignment tip will turn on the end of the stud......

Finally got it loose. Had the puller as tight as it would go without breaking.  Sprayed everything with knocker- loose & let it sit all night.  Went out this morning & taped it with a hammer & it popped loose.
